Abstract

We examined the efficacy of a new classification produced by International Union Against Cancer (UICC) in 1993 for 61 patients who underwent resection of lung cancer with intrapulmonary satellite tumor(s) during 1952 to June 1991. Survival rate after resection was calculated according to the new classification. Survival rate of patients with stage I lung cancer was 67% at four years after surgery, that with stage IIIA was 33% and stage IIIB 5% at five years after surgery. There was a significant difference between the survival of stage IIIA and stage IIIB. Five year survival of patients with N0 or N1 lung cancer was 62%, which was significantly better than four year survival (3%) with N2, N3, or NX lung cancer. Five year survival for patients with squamous cell carcinoma was 61%, which was significantly better than that (9%) with adenocarcinoma. The new TNM classification produced by UICC is acceptable in investigating lung cancer with ipsilateral satellite tumor(s). It is necessary to investigate lung cancer with contralateral satellite tumor(s). Prognosis of patients with N0 or N1 lung cancer, especially squamous cell carcinoma, even if with intrapulmonary satellite tumor(s), was relatively good after resection. Such lung can...Continue Reading
